A heat dissipating device comprises a bottom plate and plurality of heat dissipating sheets. A surface of the bottom plate is formed with a plurality of inclined recesses which are spaced with an equal space. Each inclined recess is inclined to a surface of the bottom plate and has two parallel sides, and every two adjacent recesses are spaced by a respective protruding rib. One end of each heat dissipating sheet has an inclined extending portion which has two parallel sides and is inclined to other portion of the heat dissipating sheet. The extending portions are inserted into the recesses of the bottom plate. By above structure, the heat dissipating sheets are inserted into the recesses of the bottom plate.
